We preview the best single day regular season meet of the year for you here:
We spoke to Centro about his chances in Monaco and he doesn't think he should be ignored even though he finished 7th in the Lausanne 1500 in 3:34.83 and 7th in an 800 in Lucerne in 1:49.12.
"I was a little bit disappointed with Lausanne," said Centrowitz to LetsRun.com when we spoke with him on the phone in St. Moritz on July 12th, "but I felt lots better about it after speaking with [coach] Alberto [Salazar]. He was pretty thrilled about it. He thought I was going to run 3:36, so he was pretty happy with it. So that made me feel a lot better."
As for Lucerne?
"I looked at my splits for that Lausanne race and ... I closed in 55, which I was pretty happy with," Centrowitz said. "I just couldn't get out, I wasn't getting going. So I looked at this 800 like it was close to St. Moritz (Centrowitz's European training base), it was easy to get into and just get my legs spinning a little bit. So I got what I needed out of it. I'm pretty happy that I got into that 800 before Monaco because I think that will help me wake up a little bit, wake my legs up a little bit and get after this next race a little bit more aggressively, which I plan to do."
Centrowitz said that he doesn't have a time goal in Monaco, saying simply that he wants to be "more competitive than I was in Lausanne." His PR is 3:30.40 from this race two years ago, and while that will be tough to beat, it's not hard to imagine him slicing a few seconds off his 3:34 from Lausanne.
"Every workout, I feel like I'm getting my legs back underneath me," Centrowitz said. "I think I'm definitely rounding into really good form and I'm excited about the progression I've had since USAs."
